Have used H&R Block for quite a few years. Tried Tax Act once did not like it at all. Came back to the tax software that can be trusted. If you make a mistake it will let you know.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
I have used this software for several years with E-filing of my Federal return. Just recently filed Electronically for my State Tax Return for the first time and had great results. Both State and Federal returns, were prepared, filed and then received my return all in a 2-week time frame!
